Charged Particle Dynamics in Disordered Systems: Monte Carlo Simulations of Glassy and Polymeric Electrolytes

Some recent advances in the stochastic modelling of the dynamics of disordered solid electrolytes are discussed. For doped crystalline and glassy conductors we employ the concept of ion diffusion in the presence of a random distribution of immobile counterions. The main properties of this counterion model are reviewed in the context of transport and dynamic measurements on glass. Furthermore we discuss some new results for polymeric electrolytes, with emphasis on the interplay between network dynamics of the polymer component and ion-polymer interactions. (Author)
